Astronomy 121 circa 2007 - Not Your Grandma's Solar System A new perspective on the precarious nature of life on Earth Blind good luck in several instances has enabled life to survive and evolve on Earth for 4 billion years. Life may be prevalent in the Universe, but only in RARE instances does it have the chance to evolve to complexity.
Astronomy 121 circa 2007 - Not Your Grandma's Solar System A new perspective on prospects for life elsewhere Life is more tolerant of extreme environments than previously thought. DNA analysis suggests life likely originated in volcanic vents. Life's prerequisites (especially liquid water) are more prevalent in solar systems. Planets share material. Impacts can transport life naturally from one world to another increasing the odds of survival.
